Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is

not implied.

Note 1: All card contacts are protected against any short with any other card contact.

Note 2: Method 3015 (HBM, 1500 Ω, 100 pF) 3 positive pulses and 3 negative pulses on each pin referenced to ground.
